-[[http://www.uniprot.org/uniprot/DNLJ_ENTFA DNLJ_ENTFA]] DNA ligase that catalyzes the formation of phosphodiester linkages between 5'-phosphoryl and 3'-hydroxyl groups in double-stranded DNA using NAD as a coenzyme and as the energy source for the reaction. It is essential for DNA replication and repair of damaged DNA (By similarity).

-== Publication Abstract from PubMed ==
-In an attempt to identify novel inhibitors of NAD+-dependent DNA ligase (LigA) that are not affected by a known resistance mutation in the adenosine binding pocket, a detailed analysis of the binding sites of a variety of bacterial ligases was performed. This analysis revealed several similarities to the adenine binding region of kinases, which enabled a virtual screen of known kinase inhibitors. From this screen, a thienopyridine scaffold was identified that was shown to inhibit bacterial ligase. Further characterization through structure and enzymology revealed the compound was not affected by a previously disclosed resistance mutation in Streptococcus pneumoniae LigA, Leu75Phe. A subsequent medicinal chemistry program identified substitutions that resulted in an inhibitor with moderate activity across various Gram-positive bacterial LigA enzymes.
